Abstract
Partial nephrectomy is preferable for the treatment of small renal tumors, because it spares the renal parenchima, avoiding a possible chronic nephropathy. During the preoperative evaluation of these patients, the nephrometry score is usually made. It is subject to multiple bias, which could lead to incorrect diagnosis. In this article, we expose the technical difficulties during the use of the nephrometry score. This publication has the purpose to enlighten the technical questions regarding the realization of necessary measures for the nephrometry score, as well as anatomical variations and visualization modes, focusing on technical care to be taken to avoid false information which might impair the final scoring and, thus, the report.
